ANTONIO VALLI, OF SANTA FE, ARGENTINA.

CLOCK.

Application filed May 28, 1924. Serial No. 716,438.

To all whom it may concern:

Be it known that I, ANTONIO VALLI, a sub 'ect of the King of Italy, residing at 47 6 umberto I. Street, Santa Fe, Argentina, have invented certain new and useful Improvements in Clocks, ofwhich the following is a specification.

My present invention relates to certain improvements in clocks or watches, its object being to provide a very simple and economical mechanism by which they can be transformed or converted into 24 hour clocks'or watches.

In order that my present invention may be clearly understood and easily carried into practice, a preferred embodiment thereof has been shown in the appended drawings wherein Figure 1 is a part view of an oscillating disc having thereon the figures corresponding to the 24 hours and a supplemental disc having indicating numbers.

Fig. 2 is a schematic representation of the acting mechanism and Fig. 3 is a detail of the supplementary disc.

Similar characters of reference denote same or like parts throughout the said figures.

According to the present embodiment of my invention 1 is an annular disc pivoted at 2 and capable of oscillatory movement as hereafter explained. Said disc carries a series of numbers alternately disposed such as for instance (1 to 11 and 13 to 23) as shown in Figs. 3 and 4. 5 is a supplementary disc pivoted at 6 eccentrically with respect of the first named disc, said disc being provided at a distance corresponding to 90 with indicating figures O, 12, 12 and 24.

On the axle 2, which is the main axle of the clock, there is a double cam 8 turning with said axle, said cam acting ona rod 9 guided at 10 and having at the other end a number of teeth 11 which mesh with corresponding teeth 12 of a wheel rotatably mounted on the axle 6. A do 13 is connected to said last-named wheel w ich acts in one of the directions of movement upon a stop 15 fixed to a rotary disc l i'mounted in one piece with the disc 5.

Said disc 14 has two diametrically opposed salient stops 16 which are adapted to cooperate with a stop lever 17 pivoted at 18 and having a tooth 19 at one of its ends. Springs 20 coact with the said stop-lever to hold the said stop 16 at a predetermined position. A rod 21 connected with the lever 17 has its free end resting on the cam 8.

The oscillatory movement of the annular disc is effected by means of a stop or the like 22 on the disc 5 which acts on salients 23 and 24 of the annular disc 1. A spring 25 tends to bring the rack 9 against the cam 8 or conveniently against a lever 26 pivoted at 27 which rests upon the said cam surface.

The ordinary dial of the clocks has twelve equidistant openings 7 through which the one or the other of the above named series of numbers appears, the central upper opening showing one or the other of the numbers on the supplementary disc 5.

In the position shown, the elements of the clock correspond to a few minutes after midnight. On turning the cam 8 the stop lever 17 will be set free and one hour afterwards, the salient 8 of the cam will release the lever 26, whereby the wheel 12 will be given a quarter turn, carrying therewith the dog 13 and the disc 5 as will be easily understood. Number 12 will then appear at the head opening 7. The cam continuing to turn, the rack bar 11 will be gradually raised and the wheel 12 will make half a turn in a contrary direction. After twelve hours, a contrary quarter turn of the wheel 12 will be effected with the result that the following number 12 will appear behindthe opening 7. One hour later, a like movement will follow, the result of which will be the appearance of number 24: on the supplementary disc and so on. Simultaneously, the annular disc 1 will be oscillated due to the contact of the stop 22 with one or the other of the salients 23 or 24 of the said annular disc, said stop 22 turning constantly with the said disc 5.

It is obvious that many constructional and other changes may be introduced without departing from the scope of the present invention which has been clearly set forth in the appended claiming clauses.
